Conversion of individual character encodings in Python3

a= ' I'm okay ' # # # #python3 default encoding for Unicode
# # #unicode >gb2312
 unicode_gb2312=a.encode (' gb2312 ') # # #因为默认是unicode所以不需要decode (), direct encode Chengxiang to convert the encoding such as gb2312
 print (' My gb2312 ', unicode_gb2312) # # #返回结果: my gb2312 B ' \xce\xd2\xba\xdc\xba\xc3 '
# # #gb2312 >utf8
Gb2312_utf8=unicode_gb2312.decode ('  gb2312 '). Encode (' Utf-8 ') # #当前字符为gb2312所以要先decode成unicode ( The parameter passed in decode is the encoding set of the current character and then encode into Utf-8
 Print (' I'm Utf-8 ', Gb2312_utf8) # # #返回结果: I'm utf-8 B ' \xe6\x88\x91\xe5\xbe\x88\xe5\xa5\xbd '
# # #utf8 >GBK
 utf8_gbk=gb2312_utf8.decode (' Utf-8 '). Encode (' GBK ')# # The current character set is encoded as Utf-8 to convert to GBK first decode into a Unicode character set and then encode to GBK character set
 Print ("I am GBK", UTF8_GBK) # # #返回结果: I am gbk b ' \xce\xd2\xba\xdc\xba\xc3 '
# # #utf8 >uicode
 utf8_unicode=utf8_gbk.decode (' GBK ') # # # #注意当转换成unicode时 do not need encode ()
 Print (' I'm Unicode ', Utf8_unicode) # # #返回结果: I'm Unicode I'm fine.
# # #unicode >gb18030
unicode_gb18030=utf8_unicode.encode (' gb18030 ')
 Print (' I'm gb18030 ', unicode_gb18030) # # #返回结果: I'm gb18030 b ' \xce\xd2\xba\xdc\xba\xc3 '

# # #总结各个编码的互相转换都要先转换成unicode然后通过unicode再转换成想要的编码
# #从上面可以看出gb2312, the results of gbk,gb18030 return are the same, it should be for these 3 are Chinese code, so are all downward compatible with each other
# #中国的编码最先出来的是gb2312, then GB18030, and finally GBK, the number of characters they support is also increasing in order from the first 7,000 to the present nearly 30,000
